It looks like the halfboard parts are named as follows:
[ul][li]vp_halfboard_horizontal[/li]
[li]vp_halfboard_vertical[/li]
[li]vp_halfboard_nw[/li]
[li]vp_halfboard_ne[/li]
[li]vp_halfboard_se[/li]
[li]vp_halfboard_sw[/li]
[li]vp_halfboard_horizontal_2[/li]
[li]vp_halfboard_vertical_2[/li]
[li]vp_halfboard_cover[/li][/ul]
I just set each to the same tile as their vp_frame_* counterpart, which looks decent.
